The Hummer H1 is a civilian version 4WD spawned from the military M998 Humvee, which has famously been used all over the world by our military forces for nearly 30 years. The Hummer (renamed the Hummer H1 by General Motors in 1999) was produced by AM General from 1992 until 2006, when the last one rolled off the assembly line. There have also been the smaller AM General/General Motors Hummer H2 and H3 models that have come and gone in production.
In 2013, a new option arrived for those looking to get their hands on a piece of the Humvee legacy. AM General has recently released its Humvee Civilian (C) Series Kit. With this kit, you get the aircraft aluminum riveted body, full chassis, trimmed-out interior, etc., but supply your powertrain of choice.
To the kit, you'll need to add your choice of engine, transmission, transfer case, and driveshafts. The C-Series kit is rated for a 2-ton payload and up to a 10,000-pound towing capacity, depending on the chosen powertrain. As usual, the kit uses the four-wheel independent suspension, geared hubs, and torque-biasing differentials. The chassis has been redesigned as a three-piece welded box frame.
Subassemblies are provided to the end builder from the AM General factory in Mishawaka, Indiana, and many of the components have been improved and upgraded from the past H1 components. The base kit with soft top and canvas-style soft doors will run you $59,995, and the first 50 kits will be fitted with a commemorative placard designating them as first-run vehicles.
You have a lot of options with this new kit, from building up a potent big-block V-8 gas motor or going with diesel power. We can imagine a Banks Duramax crate engine marrying a new Allison transmission to end up with a beast of a rig. If you're looking for a large 4WD with custom powertrain options, the C-Series Humvee may pique your interest. Are you ready?
Hummer Alpha H1
The epitome of the H1 line is the Alpha H1, which was produced only as a 2006 model. This highly coveted Hummer was equipped with a unique powertrain. AM General dropped a GM Duramax 6600 V-8 diesel engine and a five-speed Allison 1000 transmission in it. The truck necessitated a 2-inch body lift to accommodate the bigger 6.6L engine but got buyers a 300-horsepower turbo-diesel with air-to-air intercooling pushing 520 lb-ft of torque.
There were also other changes to the Alpha model over the standard H1. The gearing was changed, new helical-geared hubs used, the frame and drivetrain were strengthened, and systems such as the induction, exhaust, electrical, and power steering were upgraded. The designers also had to re-engineer a major portion of the cooling system and related components to properly handle the Duramax engine heat.
New, the 2006 Alpha H1 hardtop would run you nearly $140,000. The Adventure Package option would also get you front and rear Eaton ELocker selectable lockers, a 12,000-pound Warn winch, and 37-inch Goodyear MT/R tires on forged dual beadlocked wheels. The Alpha H1 still remains a highly sought-after Hummer model to this day.
